Step 1: Separate the combined inequality into two individual inequalities.
The given inequality is β1β€35β2xβ<2xβ1
This can be split into two inequalities:
- β1β€35β2xβ
- 35β2xβ<2xβ1
Step 2: Solve the first inequality.
β1β€35β2xβ
Multiply both sides by 3:
β1Γ3β€5β2x
β3β€5β2x
Subtract 5 from both sides:
β3β5β€β2x
β8β€β2x
Divide both sides by -2. Remember to reverse the inequality sign when dividing by a negative number:
β2β8ββ₯x
4β₯x
So, xβ€4.
Step 3: Solve the second inequality.
35β2xβ<2xβ1
Multiply both sides by 3:
5β2x<3(2xβ1)
5β2x<6xβ3
Add 2x to both sides:
5<6x+2xβ3
5<8xβ3
Add 3 to both sides:
5+3<8x
8<8x
Divide both sides by 8:
88β<x
1<x
So, x>1.
Step 4: Combine the solutions from both inequalities.
From Step 2, we have xβ€4.
From Step 3, we have x>1.
Combining these two, we get the combined inequality:
1<xβ€4
The final answer is 1<xβ€4β.
